The health sector plays a central role in communicating, preventing and following up on the effects of the climate and environmental crisis. Therefore, the inclusion of the topic of climate change and Planetary Health in education, training and continuing education in all health professions must be ensured. To contribute to this, the Planetary Health Academy was founded in spring 2020 by KLUG – German Climate Change and Health Alliance and Health For Future.

Our team:


As a pedagogue and adult educator, Marischa Fast worked with general practitioners for many years in order to establish high-quality further training. Her main focus is the shaping of group processes, consulting and the conception of teaching and advanced training events. At KLUG, she is now connecting her expertise with a matter of heart: designing educational processes about transformation and planetary health.


Friederike von Gierke worked as an anaesthesiologist, until she decided to put all her effort into socio-political change. At KLUG, she is part of the projects Planetary Health Academy and Sustainable Practice. She contributes her experience from the current reform of medical studies as well as from the public relations work of a climate justice group and combines her personal core topics of communication and climate with her medical expertise.



Sabine Baunach is a medical doctor and after her studies she first spent some years in humanitarian and development aid with a focus on reproductive health. Since a few years she has made Planetary Health her profession in order to bring existing knowledge into application via transformative processes. Since then, she has worked on the topic as a consultant, lecturer, and in various roles for KLUG and Health for Future.

Currently, Sabine is supporting the Planetary Health Academy team and filling in for Marischa Fast during her absence.
